This patch shall create VFs via the PCI SYS interface. Default value : $::os_service_default Sample Format : ['eth0:4','eth2:128'] For values as in sample format, the sriov_numvfs config files for eth0 and eth2 will have the values 4 and 128 respectively The SR-IOV numvfs configuration shall be persisted in /sbin/ifup-local so that, during the bootup of the compute nodes, the numvfs configuration will be restored. Change-Id: I7450b904475bdf46498d9af633416b3eba12f761 Implements: blueprint tripleo-sriov Signed-off-by: karthik s <ksundara@redhat.com>
